JACOB DINGEE, OF DOWNINGTON, PENNSYLVANIA.

Lette/rs Patent No. 93,424, dated August 10, 1869.

IMPROVEMENT 1N VNunez-commas.

The Schedule refen'edto in these Letters Patent and part of tige same.

To all whom it may concern:

Be it known that I, JACoB DINGEE, of Downington,\ in the county of Chester, and State of Pennsylvania, have invented a new and improved Milk-Cooler; and I do hereby declare that the following is a full, clear, and exact description thereogwhich will venable others skilled in the art tomake and use the same, reference being had to the accompanying drawings, forming part of this specification, in whichv Figure 1 represents a vertical central section of my improved milk-cooler.

Figure 2 is a plan or top viewof the same.

Similar letters of reference indicate corresponding parts.v

This invention relates to a new milk-cooler, which is so arranged thatthe steam produced during the cooling-process will be allowed to escape, and that the process itself will be rapid Vand thorough. One great object to be attained in milk-coolersfis facility of cleaning. Those now in use are.v mostly provided'with curved or other passages, which are dificult toA clean. v

My invention consists in the general combination of vessels, pipes, &c., whereby an apparatus having all the requisites of a goed milk-cooler is produced.

A, in the drawing, represents a tub or vessel, made of wood, lsheet-metal, or other suitable material, of slightly-inverted conical forni.

B is'another vessel, 'of similar shape, but somewhat smaller than A, so that it can be fitted into the same, as shown.

When .the vessel B is tted into A, a space is left below and around A, as shown.

The vessel B is provided with a fixed coveri 11g-plate, a, which is deeper in the centre than toward the edges, as shown in fig. 1. Y

A vertical pipe, O, of oblong cross-section, is fitted through the vessel B, and through the cover a and bottom b, of the same, as shown, it being somewhat wider at its lower than at its upper end.

A vertical angc, c, projects around the top of the Vessel B, as shown.

D is a pipe, leading from above into the vessel B, and

E is a Siphon, extending into the vessel B,.and made to project over the edge of A, as shown.

F is the distIibuting-vesseL It is composed of a perforated rim, d, conical bottom, e, and of a convex plate, j; which is, by legs y, supported above the centre ofthe bottom, as shown.

The vessel F is placed upon the vessel B, being, by

booksh, suspended from the rim c of the same.

The milk to be cooled is poured upon the plate f,

runs into the vessel F," and, through the apertures of d, upon the cover of the vessel B. It thence ows, through the pipe G, into a, and rises in A, until it flows out through a spout, i.

The water is, through the pipe D, poured into the vessel B.

As the milk is, in thin sheets, brought in contact' with the top, inside, bottom, and outside of the vessel B, it is thoroughly cooled before it escapes.

The bottom, e, has a central aperture, to allow the vapors from the milk to escape.

The Siphon serves to withdraw the water from the vessel B.

It -will be noticed that all the milk-passages can be easily reached' and cleaned.

The whole device may be enclosed in a tnbor case, G, as shown.

' 'Having thus described my invention,

I claim as new. and desire to secure by'Letters Patent- A milk-cooler, consisting of the vessels A, B, and F, the vessel B, having the vertical pipe C, the inverted conical cover a., and the supply-pipe D, while the vessel F is perforated near the rim, all substantially as and for the puipose herein shown and described. c,

.The above specic'ation of my invention signed by me, this 10th day of June, 1869.

JACOB DINGEE.
